Convert acceleration units — metres per second squared (m/s²), standard gravity (g), cm/s² (Gal), and ft/s². Useful for relating centrifugal force, g-loads and SI units.
Reference values
- 1 g (standard gravity) = 9.80665 m/s²
- 1 Gal = 1 cm/s² = 0.01 m/s² (used in geophysics)
- 1 ft/s² = 0.3048 m/s²
In the lab, acceleration most often comes up as relative centrifugal force (RCF), expressed in × g. To convert centrifuge speed (RPM) to g, use the dedicated RPM ↔ g converter.
